Does anyone have a solid works file for this trebuchet?
Floating Arm Trebuchet
We do a yearly pumpkin-chunking w/ a traditional counterweight trebuchet, but I was considering building a floating arm trebuchet. The thought of resetting it multiple times seems daunting.As a second thought, I wanted to share the trigger we built to release. The kids were having a difficult time w/ pulling the pin from the overlapping eye bolts, so we built this... much easier w/ the heavier weights. Crude image, but you get the idea...
Jeff,Resetting with that much weight was time consuming. Notice we had our weight bar set up similar to a weightlifting set, in fact, at the competition they actually had gym weights which we used instead of the concrete ones we made. The process after firing was to remove the weights one by one, then raise the arm to set position (which still took a bit of muscle when empty), then set the safety and trigger, load the weights back on one at a time using step ladders, remove the safety, and fire. If we'd have had more time and money, and the rules of the competition would have allowed, we'd have designed some sort of pulley system to simplify the reloading.
You mentioned ~750# in counterweight. Can you describe the process for resetting it?
